For my Layena I pay $11.50 for 50lbs
BOSS is $7 for 25lbs or 13.50 for 50lbs
Scratch $7 for 25lbs but I can also get 50 lbs for only $10 at my local co-op.
I only buy from co-ops, not from Atwoods or any of the commercial stores...unless I need my Orchard Grass/Timothy hey pellets for the bunnies, which only Atwoods carries.
Purina Start & Grow (the chick starter) is $11.50 for a 50lb bag. I am going to have to buy some soon too, but I hate to get 50lbs...but its better than the $4 I had to pay for 5lbs of it at Atwoods when I just had to bring those chicks home!
